<details>

* `if let` can be more concise than `match`, e.g., when only one case is interesting. In contrast, `match` requires all branches to be covered.
* For the similar use case consider demonstrating a newly stabilized [`let else`](https://github.com/rust-lang/rust/pull/93628) feature.
* A common usage is handling `Some` values when working with `Option`.
* Unlike `match`, `if let` does not support guard clauses for pattern matching.
